# Charge and conductor?

Okay, I have a feeling this is a pretty easy problem to solve, the only trouble is, my professor worded it really weirdly, so I only have half an idea of what it's asking.
Any ideas?

-----------
Let the Electric field be E at a point P near a conductiong material. Because of electrostatic induction, the force on a charge q at P will not yield E. Show, however, that the average of the fields of two equal and opposite charges +q and -q gives the correct value: E=(Fq+-Fq-)/2q.
------------
From what I can gather, it's asking me to prove the average E field of a dipole is that.

Thanks.

EDIT:
Nevermind, I just figured it out.
